Since i did some suspension upgrades i made a video at the track looking at 1 of my rear shocks, shocks where in position 8 out of 9, adjusted the traccion bars a penny thick from touching the leaf springs, tires are et street at 15 psi

I left with foot brake/3500rpm/5psi of boost, exacly 1 second after i launch im at 10 psi of boost and it slowly goes to 11 or so till the end of the 1/4 run

60´s on that run where 1.946

What exacly am i looking for? for the shocks to extend and keep extended? i see its extending the second i start to hit the throttle and it keeps extended other then the bumps at the track, our track is concrete till 60 ft and then its pavment so it has a bump on both sides :s

any input is appreciated

 

hard to tell from the vid. did it hook or spin? if it hooked, leave harder. 1.94 hooking is slow poke

 

Those shocks arent doing squat for control

 

hard to tell with such a soft launch.

 

What setting was those ranchos on

 

setting 8 out of 9

Besides having humidity weather that day, our track is not really different from a street, they only prep the first 60 or 100ft if much and by prep they only spray vht on it but that the best we can get here

i was thinking on setting the shocks to position 9 (the stiffest) and then maybe but 1 turn of load with the caltracks on the leaf springs

then launch it harder, i can boost it a little more and still hold it with my brakes

 

I would launch it harder where you're at. don't change anything if you're not spinning. once you see how it reacts with a harder launch you can make a decision from there.


was that a nailed throttle or just rolling into it?

 

Can say this when i had ranchos and toss them full stiff i could still move rear around by hand, now with afcos and only having my shocks half way i can barely move the rear...amazing how much a good shock helps

 

nailed it, 40% tps on footbrake to make the 5 psi of boost and when i let out the brakes 100% tps

this gives me some ideas i´ll test more next race season

 

i believe you but we have seen some pretty good times on ranchos for members in here so i think if i tune my current suspension i should be able to lower my 60´s
